Advantages of protected cultivation in O' Valley
1
Year-round crops
Under cover, cucumber can be grown for the whole year in O' Valley, so you can supply buyers every week instead of one open-field season.
2
Better yield and price
Plants grow without rain, hail and wind damage, so yields are higher and more even, and clean, graded produce sells at a better price, especially off-season.
3
Less water
Drip irrigation under cover uses less water than flood irrigation, and the roof keeps July's 378 mm of rain off the crop and the soil.
4
Less pesticides
Insect net on vents and doors keeps out most pests, and controlled ventilation helps with leaf disease in the humid months (May to December), so you spray less often.
5
Subsidy eligible
Polyhouse, shade net and nethouse projects in Tamil Nadu can apply for Mission for Integrated Development of Horticulture (MIDH) assistance through the state horticulture department.[6]
Which polyhouse suits O' Valley?
For polyhouse farming in O' Valley, the structure decides which months you can crop and what it costs to run. With average highs between 23°C and 32°C through the year, O' Valley suits a naturally ventilated polyhouse for most crops. Fan & Pad cooling is rarely needed; spend the budget on good ventilation, insect net and a shade screen. Plan for heavy rain in July (about 378 mm): raise the plinth, size the gutters for that month and keep drains away from the nutrient tank.
Sunlight peaks in March at about 6.4 kWh per m² a day, so add a shade screen for leafy greens in the brightest months. A nethouse, the lowest-cost option, can grow hardy crops in December to April, when it is mild and fairly dry.
Crops for O' Valley
Based on O' Valley's climate, the crops with the longest growing windows are cucumber (all year), chilli pepper (all year) and brinjal (all year). Cucumber fits all year in a naturally ventilated polyhouse. Lilium and strawberry are hard to time here, so we would leave them out of the first season. These are the crops we would plan first for polyhouse farming in O' Valley.
